Section 80

Any person who, having been sentenced to detention under this Act, is at large may (without prejudice to any other power of arrest) be arrested by any police officer or any officer of the Force or a provost officer without warrant and taken to any place in which the person may be required to be detained in accordance with this Act.

Where any person sentenced to detention under this Act is at large at any time during the period for which the person is liable to be detained in pursuance of the sentence, no account is to be taken, in calculating the period for which the person is liable to be so detained, of any time elapsing after the person was at large and before either the person is taken into custody or the person is received into a detention barrack.
